The problem

Booking a workout is a chore.

Six studio apps. A dozen schedules. A bad knee you have to remember. Traffic across town. The result is decision fatigue — so people just... skip.

73%

of fitness app users stop opening them within 90 days. Motivation isn’t the problem — friction is. (JMIR Mhealth, 2021)

apps today talk to all of them. People download six studio apps and only use two. SoFit replaces all of them with one text thread.

A new kind of hospitality

Your instructor knows the room before they walk in.

Before every class, SoFit sends the instructor a short brief on each student — injuries, focus areas, and any specific request for that day.

It’s the kind of personal touch the best studios used to deliver one student at a time. SoFit makes it work at full classes.

  • Standing notes — chronic injuries, instructors you love, the moves you avoid.
  • Today-only requests — “extra glutes today,” “light on wrists, sore from yesterday,” “tough week, take it easy on me.”
  • Opt in once, toggle anytime. Private to the instructor.
  • One short text, 30 min before class. Instructors arrive already knowing the room.

Quick heads-up for your 5:45 today —

Josh (new) — bad wrist, prefers reformer 1, ~3 months in
Sarah (regular) — knee tweak this week, easy on jumpboard
Maya (first visit) — wants gentle, mentions tight hips
Bruno (regular) — extra glutes today, light on wrists

Member-level memory tied to specific instructors is unique to SoFit. Most existing tools treat each booking as anonymous; we treat it as part of an ongoing relationship.

Why now

A wide-open lane.

We mapped the landscape. Nobody owns the consumer concierge.

AI agents sell to studios

Every AI fitness tool today is a single-studio front-desk bot. None work for the member across studios.

Search boxes don't plan for you

Existing tools help you search a catalog. They don't know you, plan for you, or book proactively.

SoFit knows you

A cross-studio concierge with memory, over text. AI + messaging finally makes this possible — and it's unclaimed.

The strategy

Studios first. Users follow.

Two-sided marketplaces lose when they chase users without supply. We picked the easy side first — independent studio owners want a lead-gen channel that respects their pricing and their member relationships.

Easy side · supply

Why studios are the easy yes

What independent studios consistently tell us they want:

  • Full-rate bookings, not discounted ones
  • No contracts, no notice periods, the ability to opt out instantly
  • Real member profiles — not anonymized handles — so the studio owns the relationship

That’s exactly what we offer: studios set the rate for each class, $0 marketplace tax, switch off anytime, full member identity, plus instructor briefs as a layer on top. Free to try, free to leave.

Hard side · demand

Why users follow once we have supply

Members are already primed to want this:

  • Trained on chat — ChatGPT hit 100M users in 2 months
  • Tired of opening 6 studio apps to plan one week
  • Personalized treatment is what they pay studios for, not a search box

SoFit gives them an agent that books their week by text, with memory that compounds and instructor briefs that make every class feel custom. The longer they use us, the smarter we get. The harder we are to leave.

The order matters. We win because the supply side is already looking for us.

The market

Start in Austin. Then everywhere.

A dense, fitness-obsessed city is the perfect proving ground — 75+ studio brands, 100+ locations across every modality.

How we get the classes

Three integrations unlock the city.

Studios run on a handful of booking platforms. We plug into the platforms, not 100 studios one by one.

Flagship

Mariana Tek

~165 [solidcore] US studios. ~89 Barry's globally. 4 in Austin. Plus Pvolve. Solidcore targets 250 US by 2028; Barry's targets 200 globally by 2030.

One platform partnership for technical access — then each chain's corporate office activates its full network with a single internal switch. Solidcore corporate “yes” = every Solidcore in the country online.

The long tail

Mindbody

The default for independent studios. Free developer sandbox means we can build the live integration today. 40+ Austin studios on Mindbody alone.

Low-friction

Momence + Pike13

Modern self-serve APIs for newer studios — incremental coverage with minimal onboarding.

The chain unlock

Two corporate “yes”es — Solidcore + Barry's — puts ~230 US locations on SoFit in a week. National coverage with two emails, not 230 separate integrations.

Built on a normalized model so every platform plugs in behind one interface — the standard architecture for spanning multiple booking systems.

Why it’s free

No fees. No subscriptions. For now.

SoFit is a personal project, not a startup. I built it because I wanted it to exist for myself. Free for members, free for studios today — if there’s real usage, I’ll think about what monetization could look like later. No promises either way.

Member

Free. No subscription, no per-class fee. You pay the studio at the studio’s normal rate — card on Stripe, SoFit never touches it.

Studio

Free. Charges land in their bank at full drop-in rate, daily payouts via Stripe Connect. SoFit takes $0 from any transaction.

SoFit

$0 from anyone. Personal project. No marketplace cut, no lead-gen fee, no subscription tier. Just a thing I’m building because I wished it existed.

I built it for myself first. I was tired of opening eight different apps to plan a workout, googling whether a class would hurt my back, and having to re-explain my injuries to every new instructor. SoFit fixes that. If people end up actually using it, I’ll figure out monetization down the line — for now, it’s free for everyone.

The roadmap

Where this goes.

Own one micro-market, then expand. Studios first, members follow.

Clone the playbook

Every fitness city looks like Austin. Same platforms, same model, new map.

Why this. Why now.

The next wave of boutique fitness isn’t an app — it’s an agent.

SoFit is the one your members are about to text. Be the studio it recommends. Or be the one it doesn’t.

3 years

Until every active member has an AI agent planning their week. ChatGPT hit 100M users in 60 days — members are already trained on chat. Fitness is just catching up.

First in

Studios that join SoFit at the start get founding-partner placement, instructor briefs from day one, and shape the product instead of inheriting it.

Or out

The ones that wait will spend the next decade explaining why they’re not on the agent their members text every week. The math doesn’t get easier from there.
